SIPHON-HEAD.

Specification of Letters Patent.

Patented Jan. 12, 1915.

To all whom t may concern Be it known that I, CHARLES Dn LUKAcsE- vrcs, a citizen of the United States, residing at l/Vest Nutley, in the county of Essex and State of New Jersey, have invented new and useful mprovements in Siphon-Heads, of which the following is a specification.

This invention relates to improvements in siphon heads, of the general type disclosed in my prior' U. S. Patents No. 1,040,226, granted Oct. 1, 1912, and No. 1,061,857, granted May 13, 1913.

The inventionv is directed to certain improvements in details of structure and arrangement which vconcern the construction of the valve of the head wherebythe said valve and its appurtenancesl have great lassemblage of the siphon head upon the bottley neck ywhereby the' head is accurately alined with the bottle and the joint between said neck and said head is effectively sealed, regardless of any irregularities `or other defects `of the surface of the mouth of the bottle; and the assemblage of the siphon tube relatively to the head whereby said tube is strongly supported, is not liable to displacement, and may be readilyl and quickly applied to and removed from the head.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure l is a vertical sectional view of a siphon head in which 'the features of the invention are incorporated; 'Fig'. 2 is a view showing in detail, by way of elevation and section, the variousfelements employed in the valve stem construction; Fig. 3 shows, in plan and in sectional detail, the construction of the elastic valve head; Fig. 4L shows in vertical section the organized relation of the metal lvalve stem and the elastic valve head; Fig. 5 is a view showing in plan and Vsectional detail the valve operating `knob and its immediate appurtenances;

Figs; 6 to 10 are views showing in plan and sectionaldetail various elements which vparticipate in the assemblage of the siphon head upon the bottle neck and in the connection' of the siphon tube and the siphon head. Similar characters of reference designate corresponding parts throughout the several views.

The improvements are illustrated in connection with a porcelain head, designated generally as l, and having its lower end in the `form of an enlarged socket 2, which fits over the bottle neck 3 and is held in position by a suitable means, such, for example, as the coperating securing rings 4: and 5, associated with the socket and with..the neck respectively.

The head 1 is formed inwardly of the y socket 2 with a bell-shaped or generally .globular cavity 7 which, 'at its lower end,

communicates with said socket and at its upper end communicates with an axially disposed'liquid conducting passage 8, from which branches the usual liquid discharge duct 9. The cavity incloses a bell-shaped member 10 of hard or relatively hard rubber and this member 10 serves four functions; lirst, to seal the joint between the bottle neck and the siphon head against the escape of gas from the bottle through any pores or interstices of the siphon head; second, to furnish support for the siphon tube 6 and to constitute a connection between said tube and the siphon head; third, to provide a housing for the valve; and fourth, to maintain the siphon head in perpendicular alinement with the bottle and to provide for the ecient and gas-tight connection of said head and bottle, regardless `of any irregularities or other defects of the surface'of the mouth of the bottle.

The member 10 is provided with a circumscribing annular flange '1l to engage kover the mouth of the bottle, and with an annular depending flange 12, which projects into the mouth of the bottle and is internally threaded to receive an externally threaded hard rubber sleeve 13, which carries the siphon tube 6. 'It is preferred to interpose sealing gaskets between the member 10 and the parts adjacent thereto. Thus, a gasket 14 is arranged between the flange 11 and the upper surface of the` bottle neck; a gasket 15 is arranged between the upper portion of the member 10 and the upper portion of the cavity 7 and a gasket 16 is arranged between the flange 12 and a flange 17 which circumscribes the sleeve 13. The member 10, at its upper end, is formed with an opening 18 which alines with the passage 8, and adjacent and below said opening with a valve seat 19. The valve is designated geny erally by the numeral 20, and its stem projects through the opening 18, while its head is disposed within the internal cavity of the member 10 and coperates with the valve seat 19. The cavity 7, as above stated, is of -generally globular or bell-shaped form and lthe external surface' of the member 10 is similarly and conformably fashioned. Where a gasket is interposed between the member 10 and the wall of the cavity 7 as in the construction shown, said gasket, i. e. the gasket 15, has a convex outer face and is preferably of concavo-conveX form.

By virtue of the relation of the generally globular adjoining faces of the cavity 7 and the member 10, the siphon head can always be held in perpendicular alinement with the bottle, notwithstanding that the Vmember 1,0 may occupy a slightly canted position, by reason of irregularities or other defects in the upper surface of the bottle neck.

Owing to the fact that gas-tight seals are provided between the member 10 on the one hand and the bottle neck and the siphon head on the other hand, any leakage of gas when the valve is in closed position, is effectively prevented.

The valve 2O is preferably of the construction shown in the drawings and comprises the relatively thin metal stem 21, the elastic valve head 22, the hard rubber sleeve 23 which surrounds the stem 21 and clamps the valve head on said stem, and the nuts 24 mounted upon the threaded upper portion of the stem and engaging the upper end of the sleeve 23 to cause the latter to eXert clamping pressure upon the valve head.

The rubber valve head 22 is held with strong pressure against the seat 19 and in order that said valve head may be rigidly supported, and hence, pressed securely against said seat, and at the same time may not be liable to wear or to become loose upon or stripped from the lower end of the stem 21, and further, in order that no area of metal, however small or minute, may be eX- posed, the construction shown in the drawings is adopted, according to which the valve head 22`is in the form of a cone, the valve stem 21 terminates at its lower end in a conical or flaring enlargement 25 which fits in a conical or flaring recess 26 in the valve head 22, and the sleeve 23 has a conical or flaring enlargement 27 at the lower end of its bore which receives the upper portion of the valve head and by virtue of which the sleeve acts with clamping pressure on the valve head andthe metal vof the stem is not only concealed, but is sealed against the access thereto of any corrosive liquid or gas.

The head1 is formed above the passage 8 with a web 28 having a central opening, and the valve stem 21 and also the sleeve 23 project through the opening 18 in the upper end of the member 10, through the passage 8 and through the opening-in the web 28. Above the web 28 the head 1 is formed with a socket 29 in which works the operating knob 30. The valve rstem 21 has its upper end secured to the knob 30 and the latter has an internal cavity in which is mounted an expansive coil spring 31. The spring 31 maintains the closed relation of the valve and surrounds the stem 21, said spring at its upper end engaging the knob 30 and at its lower end engaging the web 28. The opening in the web 28 is sealed by a' gasket or packing ring 32, which snugly surrounds the sleeve 23. The ring 32 is preferably located at the upper side of the web 28 and in order to protect said ring Lagainst wear, a metal washer or other wear ring 33 is imposed thereon to take the thrust of the spring 31.

Instead of the usual direct-thread connection between the upper end of the valve stem and lthe operating knob, the construction shown in the drawings may be advantageously employed. according to which the knob 30 has a central opening 34 of substantially greater diameter than the valve stem 21 and formed with threads or serrations and a soft metal ring 35 is cast in this opening, the metal of said ring interlockingly engaging in the threads or serrations of the opening 34 and the threads of the valve stem 21. The opening 3ft and the valve stem 21 originally define an annular mold space into which the metal forming the ring 35 is poured, and said mold space is closed at its lower end by a ring 36 arranged at the upper end of the internal cavity of the knob 30 and receiving the thrust of the spring 31.

In order to limit the downward movement of the knob 30 the socket 29 is formed with a step 37 and said knob is formed with an external shoulder 38 for engagement with said step. In order to prevent rotation of the knob 30 the latter is formed with a facet 39 below the shoulder 38 and the socket 29 is formed with a similar facet below the step 37.

In assembling the siphon head the valve parts shown in Fig. 12 are first organized in the manner explained. The member 10 is then centered in the cavity 7 and the valve stem is introduced into the cavity of said member and is pushed through the opening 18, the passage 8, and `the opening 28, into the socket 29. The nuts 24 are preferably round and of the same diameter as the sleeve 23, in order to avoid interference "with the assembly of the'valve in the siphon head, in

the manner just stated. The spring 31 is next placed in position in the socket 29 and the knob 30 is then fitted in said socket over said spring. The knob `and valve stem are so held by any suitable appliance that the annular mold cavity, previously referred to, is defined, the ring 36 forming the bottom of this cavity, as already explained. Thereupon, the ring 35 is cast in said cavity, and when the metal of said ring sets a secure connection is provided between the valve stem and the knob, as is obvious. In case it is desired to dismantle the valve, a soldering iron or other suitably heated implement is used to soften the ring 85, whereupon the lmob 30 may be disconnected from the valve stem and the parts dismantled as is obvious. The use of the cast ring 35 is of advantage in that it protects the knob 30 against fracture and promotes the facility of assemblage and disassemblage of the parts of the siphon head.

The upper end of the siphon tube 6 is cemented in the sleeve 13 and to facilitate the union of said tube and said sleeve, the central opening of the latter terminates in flaring enlargements Li0, in which the cementing agent is introduced. That portion of the sleeve 13 below the flange 17 is formed with openings or recesses 41 for engagement by the jaws of a Spanner or other suitable implement employed to rotate the sleeve 13 in eifecting the connection or disconnection of said sleeve and the member 10.

The valve head 22 holds the member 10 in position in the cavity 7 and thus supports said member and the siphon tube whenever the siphon head is in detached relation.

The siphon head described, although of extremely simple structural nature and being relatively inexpensive to manufacture, is particularly efficient in use, in that effective provision is made against the escape of gas, compensation is made for irregularities or other defects in the upper surface of the bottle neck, the siphon tube is ystrongly supported, cushioned against jars, and removable and replaceable with facility, the. valve is organized with especial regard to sanitation, and is especially effective in its action and durable in its nature, the assemblage and disassemblage of the parts of the siphon may be accomplished easily and quickly, and no particular care in surfacing any part of the internal cavity of the head proper is required, since the efficiency of the seals and of the seating of on the exact evenness or uniformity of the surfacesof the cavity of the Siphon head and 4 the valve body does take directly against a seat formed in the member 10 rather than against a seat formed in the siphon head proper. This last advantage is particularly important in cases where the siphon head is made'of porcelain or like material, which,

the valve does not depend" by reason of its porous nature and the treat'- ment required in manufacture, is very likely to develop surface irregularities, and, if not effectively sealed, to allow the leakage of gas.
